A Wireless Soft Optical Blood Sensor for Colonoscopy
Advanced Sensor Research, EarlyView.This works presents an “add‐on” wireless soft optical blood sensor for the traditional colonoscopy. It can reliably detect bleeding behind the colonoscope's distal tip camera via optical absorption, without optical fibers, and wirelessly transmit data to the processor.

On some differences between number fields and function fields
, 2016 The analogy between the arithmetic of varieties over number fields and the arithmetic of varieties over function fields is a leading theme in arithmetic geometry. This analogy is very powerful but there are some gaps.

Advanced Theory and Simulations, EarlyView.This work presents a combined analytical–computational approach to quantify the influence of aspect ratio and anisotropic orientation on the percolation behavior of penetrable rectangles. The proposed model reliably predicts the geometric percolation threshold and electrical conductivity of 2D networks, with power‐law fits showing strong agreement with

Positive degree and arithmetic bigness
, 2008 We establish, for a generically big Hermitian line bundle, the convergence of truncated Harder-Narasimhan polygons and the uniform continuity of the limit.

Advanced Science, EarlyView.A healthcare toilet system is introduced to passively measure defecation behavior. Real‐time data on stool dropping duration, thickness, and a newly defined “eu‐tenesmus” interval show correlations with stool form and gender differences. Results from 45 defecation events reveal a promising method for comprehensive defecation analysis.

On the normalized arithmetic Hilbert function [PDF]
Algebra & Number Theory, 2015 Let $X$ be a subvariety of dimension n of the projective space over $\overline{\mathbb{Q}}$, and $H_{norm}(X;D)$ the normalized arithmetic Hilbert function of $X$ introduced by Philippon and Sombra. We show that this function admits the following asymptotic expansion $H_{norm}(X;D) = \frac{\widehat{h}(X)}{(n + 1)!}D^{n+1} + o(D^{n+1})$ where $\widehat ...

From Ancient Techniques to Modern Solutions: In Situ Synthesis of C‐S‐H for Sandstone Conservation
Advanced Science, EarlyView.Herein, this work presents a paleo‐inspired approach to synthesizing and optimizing C‐S‐H‐based grouting mortars for conserving the sandstone of Beishan Grottoes, Dazu Rock Carvings, China. By achieving an optimal recipe compatible with natural sandstone, this work demonstrates the pivotal role of hydrogen bonding in the adhesion between C‐S‐H mortars ...

Advanced Science, EarlyView.Cu5%‐MoS2 with dual Cu and Mo active sites enables efficient photothermal synergistic catalysis of the CO2–H2O system for ethanol production. The catalyst achieves a high ethanol yield of 3.1 mmol·g−1·h−1 with 88.35% selectivity, showcasing exceptional performance and selectivity under mild conditions. Abstract The catalytic conversion of CO2 into high‐

IEEE Annual Symposium on Foundations of Computer Science, 2019 We exhibit a randomized algorithm which given a square matrix $A\in \mathbb{C}^{n\times n}$ with $\Vert A\Vert\leq 1$ and $\delta > 0$, computes with high probability an invertible $V$ and diagonal $D$ such that \begin{equation*}\Vert A-VDV^{-1}\Vert\leq\

Advanced Science, EarlyView.Compared with those on the pTi surface, macrophages on the TNTs surface present reduced myosin II contractility, which facilitates the nuclear translocation of the UTX. This reduction decreases the enrichment of the repressive H3K27me3 histone modification at the Abca1 gene locus, which promotes the transcription and protein expression of ABCA1 ...
